Common Power Strip Cable Materials Explained

Understanding the Pros, Cons, and Safety Implications

1. Pure Copper (100% Copper)

Best for: High-end power strips, heavy-duty devices.

Advantages

  • Highest conductivity (≥98%) for minimal energy loss.
  • Heat-resistant, durable, and corrosion-resistant.
  • Safe for long-term use with 2000W+ devices.

Disadvantages 

Higher cost than alternatives.

2. Aluminum

Best for: Low-cost, temporary-use power strips.

Advantages

Lightweight and affordable.

Disadvantages:

  • Low conductivity (~60% of copper), causing energy waste and overheating.
  • Prone to oxidation and fire risks over time.

3. Copper-Clad Aluminum (CCA)

Best for: Mid-range products balancing cost and performance.

Advantages:

Cheaper than pure copper, better conductivity than pure aluminum.

Disadvantages:

  • Copper layer wears off over time, reducing safety.
  • Not suitable for high-power devices.

4. Tinned Copper

Best for: Humid environments or industrial applications.

Advantages:

  • Tin coating prevents oxidation and corrosion.
  • Retains 95%+ conductivity of pure copper.

Disadvantages:

Slightly higher cost than pure copper.
